Drinking Water Features

  1. Women Are The Secret Weapon For Better Water Management
    10/24/2018

    In the 1980s, the government of Malawi began providing piped water to low-income households in 50 districts, establishing community-run tap committees to collect bills and manage systems. Men made up 90 percent of committee memberships — and problems quickly became apparent.

  2. Identifying The Best Lead Sampling Techniques To Protect Public Health
    10/23/2018

    If lead is found in drinking water, it is important to identify where it is coming from within the water system — that means taking samples at every stage, from the distribution system all the way to the plumbing system inside the home, also known as premise plumbing.

  3. How To Provide Effective Disinfection With No Hazardous Chemicals
    10/19/2018

    Reliable and effective disinfection is a cornerstone of water and wastewater treatment, needed to protect public health. Most drinking water utilities are required to maintain a minimum disinfectant residual in the distribution system. This ensures adequate chemical was applied and remains in the system to kill pathogens. The most commonly used disinfectants — chlorine gas and bulk sodium hypochlorite — require operators to regularly handle these hazardous chemicals.

  4. How Drought And Other Extremes Impact Water Pollution

    A Q&A with Berkeley Lab hydrological science expert Bhavna Arora, who explains how unseasonably warm weather and drought can affect water quality

  5. Coping With Mixed-Source Water Quality And Corrosion Challenges
    10/12/2018

    When it becomes necessary to expand or blend water supply sources, variety is not necessarily the spice of life. Whether new water sources are surface water or groundwater, fresh, brackish, seawater, or water recovered from aquifer storage, they can ultimately impact water treatment plant (WTP) operations and finished water quality — including compliance with the U.S. EPA Lead and Copper Rule.

  6. New Testing Method For Lead And Arsenic In Contaminated Soil Saves Money And Protects Public Health
    10/10/2018

    EPA recently validated an innovative new technology to guide the cleanup of soils contaminated with arsenic and lead. The new laboratory method, based on a “virtual stomach” that mimics human digestion, estimates the bioavailability of arsenic and lead in soils quickly and inexpensively relative to animal models. This method will increase the accuracy of Human Health Risk Assessments, potentially reducing remediation costs.

  7. How To Mitigate Biofouling In Your Industrial Process Using 2nd Generation ATP
    10/9/2018

    Microorganisms can wreak havoc in industrial processes in a number of ways – from slime formation that causes paper breaks and excessive downtime in papermaking facilities, to costly recalls of spoiled final product. Consequently, an effective microbiological control program, which includes accurate and reliable monitoring, is critical for maintaining an efficient process and final product quality.

  8. How Is California Affected By The Clean Water Act Mess?
    10/5/2018

    Just when we thought the jurisdictional and regulatory issues concerning the federal Clean Water Act and the resulting implications could not get more complicated, recent developments have put that possibility to rest.

  9. Help For São Paulo’s Complex Water Woes: Protect And Restore Forests
    10/1/2018

    In 2014, São Paulo nearly ran out of water. Schools closed, crops faltered and reservoirs were left at a tiny 5 percent of their capacity for the city and its surrounding population of 22 million. It was the worst drought in eight decades.

  10. What’s In Your Water? An Updated Analysis
    9/24/2018

    NRDC’s new analysis of the most recent EPA data finds that nearly 30 million people in the United States drank water from community water systems that violated the EPA’s Lead and Copper Rule between January 2015 and March 2018.
